Duo Labs purchased a stack of OEM (Original Equipment Manufacturer) laptops to see how secure they were. The idea was to judge how secure the laptops were based on network traffic and network presence. Some problems immediately jumped out at us, like the eDellRoot issue, but a few other issues took a bit more sorting through. The main attack scenario to consider is not the new laptop user at home – at least from a network perspective – but, rather, when new laptop users grab their fresh purchase and heads out the door to the coffee shop, the hotel on a trip.”]
